Emuge GF342106.5013 Thread Mill 1/2-13 4 Flute Solid Carbide

Product Description

The EMUGE GF342106.5013 is a helical flute thread mill designed for cutting internal UNC threads to a 1/2-13 specification. Built from solid carbide and coated with TiCN for extended tool life and heat resistance, this mill produces accurate threads in a single helical pass. It carries four right-hand flutes, a cutting diameter of 0.4070 inches, and a length of cut of 1.2670 inches. Overall length is 3.7800 inches with a 14.00 mm (0.5512 inch) shank diameter. Coolant-through capability supports chip evacuation during deep or tight-tolerance threading operations. Licensed machinists and CNC operators use this tool in production and precision machining environments.

This thread mill is suited for internal threading applications in ferrous and non-ferrous materials where a helical milling approach is preferred over tapping. The 1/2-13 UNC thread form and 13 TPI configuration make it appropriate for standard fastener hole preparation in machined components. It is intended for use in CNC machining centers with helical interpolation capability, where the tool path diameter is adjusted to produce the finished thread form. Typical applications include fixture plates, mechanical assemblies, and precision enclosures requiring reliable UNC threaded inserts.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• TiCN coating reduces friction and extends tool life in ferrous and stainless materials
• Four right-hand helical flutes for balanced cutting and efficient chip removal
• Coolant-through design supports chip evacuation and temperature control during threading
• 1/2-13 UNC internal thread form with 13 TPI for standard fastener compatibility
• 14.00 mm shank diameter provides secure toolholder engagement

Compatibility

Designed for use in CNC machining centers capable of helical interpolation for cutting 1/2-13 UNC internal threads.

Installation Notes

Installation and operation should be performed by qualified CNC machinists familiar with helical thread milling programs and toolpath compensation. Confirm spindle speed, feed rate, and helical pitch settings in the CNC program before running the tool in the workpiece. Power down and lock out the machine before changing or inspecting the tool in the holder. Use appropriate collet or end mill holder sized for the 14.00 mm shank to ensure runout is within acceptable limits for thread accuracy.
